MKS Granville Phillips 355 Micro-Ion Bayard-Alpert Hot Cathode Vacuum Gauge, Dual Tungsten Filaments, 3/4 inch Tube Port, Stainless Steel Encased. MKS Granville Phillips Part Number: 355001-TA The World’s Smallest Ionization Gauge. The Micro-Ion Gauges occupy less than 10% of the volume of conventional glass gauge or nude gauges, allowing easy installation in complex, tightly packed vacuum systems. With high performance patented dual ion collector design increasing electron path length and ion collection efficiency providing high performance in a small volume. Having long term stability, the grid windings are attached to the grid posts every 180° for greater sensitivity and stability. The dual filaments helps provide long gauge life. Unscheduled downtime is avoided by using the second filament as a back-up until the gauge can be replaced during regular maintenance procedures. These gauges have cooler operation, at only 8% of the power consumption of a traditional glass or nude gauge, the Micro-Ion Gauge generates significantly less heat-related process or experiment disturbances. Port shield protects the electrode assembly from damage during assembly or vacuum chamber maintenance, and provides a stable electrical environment for improved measurement performance. They have all-metal enclosures which prevents grid and filament damage during mounting and eliminates the risk of glass breakage. These gagues come with a wide selection of vacuum fittings, making installation very simple in your vacuum systems.
